Abstract
The invention discloses a moving core print blank and a method for manufacturing a moving core print by using the blank, belonging to the basic non-cutting processing of metal pipes. The invention aims to solve the technical problem of designing a moving core print blank and a method for manufacturing the moving core print by using the blank. The technical scheme of the invention is that the moving core print blank comprises a fixed diameter and a large diameter, and center holes are arranged at the centers of two ends of a core print. A method for manufacturing a moving core head by using a moving core head blank comprises the procedures of grinding, sizing and large-diameter molded surface, and comprises the steps of firstly, finely processing tip holes at two ends of the moving core head on an inner circular grinding machine to enable the size precision and the coaxiality of the tip holes to meet the requirements, and respectively grinding, sizing and the large-diameter molded surface on an outer circular grinding machine by taking the tip holes as positioning references to manufacture the moving core head. The die is used for drawing the metal pipe.
Description
Technical field
What the present invention relates to metal pipe material does not have machining substantially, and particularly a kind of drawing dialled metal tube with the floating core head blank with the method for this blank manufacturing floating core head.
Background technology
Refrigeration and air-conditioning equipment copper alloy tube, the general method that draws that adopts is made desired pipe, the big footpath size of the floating core head in the Drawing die set and the precision of sizing size with and the precision of axiality very high, in order to improve the anti-wear performance of core print, prolong its service life and all adopt Hardmetal materials to make, this superhard material can only adopt grinding, and allowance is unsuitable big.For carbide alloy floating core head blank, existing processing method is, make the big footpath of benchmark grinding cylinder with the sizing cylinder, make benchmark grinding sizing cylinder with big footpath again, because processing method with different twice clampings of datum level, the axiality of core print two cylinders is difficult for guaranteeing that qualification rate is low, the manufacturing cost height of copper pipe.
Summary of the invention
The technical issues that need to address of the present invention are a kind of floating core head blanks of design and with the method for this blank manufacturing floating core head, with the carbide alloy floating core head that this blank and method are made, and the axiality height of its big footpath and sizing.Technical scheme of the present invention is, a kind of floating core head blank includes sizing and big footpath, and it is characterized in that: the center at core print two ends is provided with center hole.2, a kind of method of making floating core head with the floating core head blank, include grinding sizing, big footpath profile operation, it is characterized in that: at first the center hole to the floating core head two ends carries out fine finishining on internal grinder, its dimensional accuracy and axiality are met the requirements, make location benchmark grinding sizing and footpath profile respectively greatly on cylindrical grinder with this center hole, make floating core head.The present invention makes the location benchmark owing to be shaped on technology at the two ends of carbide alloy floating core head with center hole, thereby the form and position tolerance precision height of the made core print of the present invention, the remarkable advantage that yield rate is high.
Description of drawings
Fig. 1 is a carbide alloy floating core head blank schematic diagram of the present invention; Fig. 2 is the schematic diagram with top clamping location core print grinding core print sizing; Fig. 3 is the schematic diagram with the big footpath of core print processing core print, top clamping location profile; Fig. 4 is a carbide alloy floating core head finished product schematic diagram of the present invention.
The specific embodiment
In conjunction with above accompanying drawing the present invention is elaborated, the present invention is in order to solve the low difficult problem of axiality that causes with twice different location of sizing and big footpath benchmark, at core print blank two ends false ceiling hole 3 is set, thereby can avoids with sizing 1 and big footpath 2 twice different location benchmark problem.Core print is a Hardmetal materials, to on blank, process center hole, its processing capacity is very big, the manufacturing cost height, therefore can when slug press, produce center hole 3 (referring to Fig. 1), the blank center hole is repaired on internal grinder with diamond grinding head earlier then, obtained the satisfactory center hole 3a of precision.Make clamping location benchmark with above-mentioned center hole 3a, with top 5 location, with the big footpath 2 of heart carrier folder blank, on cylindrical grinder, grind the sizing cylinder on request with emery wheel 4, obtain satisfactory sizing 1a, press from both sides the good sizing cylinder of grinding with heart carrier then, on cylindrical grinder, use the big footpath of formed grinding wheel grinding shape face, obtain satisfactory big footpath 2a, grind the chamfering at core print two ends then, the surface of core print is polished promptly make the effective carbide alloy floating core head (referring to Fig. 4) of draw metal at last.
Claims (2)
1, a kind of floating core head blank includes sizing and big footpath, and it is characterized in that: the center at core print two ends is provided with center hole.
2, a kind of method of making floating core head with the floating core head blank, include grinding sizing, big footpath profile operation, it is characterized in that: at first the center hole to the floating core head two ends carries out fine finishining on internal grinder, its dimensional accuracy and axiality are met the requirements, make location benchmark grinding sizing and footpath profile respectively greatly on cylindrical grinder with this center hole, make floating core head.
